Darkthrone's 'A Blaze in the Northern Sky' is quite the classic. Furze, of course - Necromanzee Cogent and UTD are great. Emperor's 'In the Nightside Eclipse'. If you want to go back a bit to the roots of BM, check out Bathory's 'Under the Sign of the Black Mark' - it's their 3rd album but I'd say their best.
